Woodward 5464-334 – 8-Channel Analog Input Module | MicroNet TMR Platform
Engineering Background
The Woodward 5464-334 is a precision analog input module engineered for the MicroNet TMR (Triple Modular Redundancy) turbine control platform. Designed to meet the demanding signal-acquisition requirements of gas turbine, steam turbine, and compressor control systems, this module provides eight independent analog input channels with high-resolution conversion and deterministic scan rates. It is a critical front-end component in safety-rated control architectures where signal fidelity and channel isolation directly impact plant availability.
Product Positioning
The 5464-334 targets procurement engineers and control system integrators sourcing certified replacement or expansion modules for existing Woodward MicroNet TMR installations. It is a direct OEM-equivalent part, fully compatible with the MicroNet TMR backplane and I/O bus, and is available from Konmask.com as a tested, traceable unit with full documentation support.

Engineering Advantages
- TMR Architecture Compatibility: Designed for triple-redundant voting logic; supports 2oo3 signal selection for safety-critical loops.
- High Channel Density: 8 independent channels per slot minimizes rack space and reduces system cost per I/O point.
- Galvanic Isolation: Eliminates ground loops and protects the control system from field-side transients and noise.
- Deterministic Scan: Synchronized analog acquisition ensures consistent control loop timing across all redundant controllers.
- Hot-Swap Capable: Supports online replacement in MicroNet TMR chassis without system shutdown (subject to system configuration).
- OEM Traceability: Each unit supplied with Woodward part number label and serialization for maintenance records.
System Architecture & Signal Flow
In a MicroNet TMR system, the 5464-334 module resides in the I/O expansion chassis and connects to the TMR controller via the proprietary backplane bus. Field transmitters (4–20 mA loops or voltage sources) wire directly to the module’s terminal block. The module performs A/D conversion on each channel and presents digital values to all three redundant controller CPUs simultaneously. The TMR voting logic in the CPU modules then selects the median value for use in the control algorithm, ensuring that a single-channel failure does not propagate to the control output. This architecture meets IEC 61511 SIL 2 / SIL 3 requirements when applied within a validated Woodward MicroNet TMR system design.
